[I] Missing Codec for Message Type 111 (TYPE_RM_DELETE_UNDOLOG) [incubator-seata-go]
0x-infinity opened a new issue, #1016:
URL: https://github.com/apache/incubator-seata-go/issues/1016
### 讨论详情
## Problem Description
When the seata-go client runs for approximately 2-3 minutes, it encounters a codec decode error. The TC server (Seata 1.8.0+) sends a message with type code 111 (`TYPE_RM_DELETE_UNDOLOG`), but the seata-go client does not have a registered codec to decode this message type.

**Configuration file** (`conf/seatago.yml`):
```yaml
seata:
application-id: test-app
tx-service-group: default_tx_group
registry:
type: file
config:
type: file
```
**Steps to reproduce:**
1. Start Seata TC Server (v1.8.0 or later)
2. Run the above code
3. Wait approximately 2-3 minutes after the transaction completes
4. Observe the error logs showing message type 111 decode failure
## Root Cause
The TC server periodically sends `UndoLogDeleteRequest` (message type 111) to Resource Managers to clean up old undo log records. However, seata-go is missing the necessary components to handle this message:
1. **Message Structure Field Type Issue**: `SaveDays` field has wrong type `MessageType` instead of `int16`
- Location: `pkg/protocol/message/request_message.go:132-136`
2. **Missing Codec**: No codec implementation for `MessageTypeRmDeleteUndolog`
- Expected location: `pkg/protocol/codec/undolog_delete_req_codec.go`
3. **Missing Processor**: No message processor to handle this request
- Expected location: `pkg/remoting/processor/client/rm_delete_undolog_processor.go`
4. **Missing Registration**: Codec and processor not registered in initialization
- Files: `pkg/protocol/codec/codec.go` and `pkg/remoting/processor/client/init.go`
## Message Type 111 Definition
```java
short TYPE_RM_DELETE_UNDOLOG = 111;
```
```java
public class UndoLogDeleteRequest {
private String resourceId;
private short saveDays;
private BranchType branchType;
}
```
